Docker with salt - Issue with PIP

[Jon Langemak]

I started playing around with the docker modules for Salt on Centos7 and there were a couple of PIP modules that I needed or needed to update.  To do so, I use the following states...

docker-py:

  pkg.installed:

    - name: python-pip

  pip.installed:

    - name: docker-py

    - reload_modules: True

    - require:

      - pkg: python-pip

six:

  pip.installed:

    - reload_modules: True

    - upgrade: True

    - require:

      - pkg: python-pip

These work well, but it seems that I need to reload the salt-minion on the client before I can use any of my actual docker states.  I get these errors until I reload the salt-minion service...

Comment: State 'docker.pulled' was not found in SLS 'docker'

Any ideas why this is?

Thanks

Yes because the docker salt state was loaded before you installed the python requirements, you need to add reload_modules: True at the end of pip.installed: docker-py, see the documentation here: https://docs.saltstack.com/en/develop/ref/states/index.html#reloading-modules

Im confused.  I already tell it to reload_modules on that state...

docker-py:

  pkg.installed:

    - name: python-pip

  pip.installed:

    - name: docker-py

    - reload_modules: True

    - require:

      - pkg: python-pip

What am I missing here?  What you say makes sense, but I think Im already doing it.  

[Boris FELD]

Do the state using docker.pulled require pip: docker-py?

[Jon Langemak]

Heres my entire state...

I tried changing the layout of the PIP stuff a bit since I thought you were indicating I was out of order.  

#Install base packages

bridge-utils:

  pkg.installed

net-tools:

  pkg.installed

device-mapper:

  pkg.latest

python-pip:

  pkg.installed

six:

  pip.installed:

    - reload_modules: True

    - upgrade: True

    - require:

      - pkg: python-pip

docker-py:

  pip.installed:

    - reload_modules: True

    - require:

      - pkg: python-pip

#Install docker, enable it, and run it

docker:

  pkg:

    - installed

  service:

    - running

    - enable: true

#Take care of firewalld

firewalld:

  service:

    - dead

    - enable: false

web_8080_image:

  docker.pulled:

    - name: jonlangemak/docker:web_container_8080

web_8080:

  docker.running:

    - container: web_8080

    - image: jonlangemak/docker:web_container_8080

    - ports:

      - "8080/tcp":

        HostIp: ""

        HostPort: "80"

I'm not sure but could you try to add reload_module: True to pkg.installed: docker? Maybe the docker client tries to connect to the daemon on import.

[Jon Langemak]

Ok - I'll try that.  Any other tips on how to debug this?  Seems odd that the fix is to restart the salt-minion service.

[Jon Langemak]

Yeah - That didnt help.  I feel like Im missing something simple here.

[Boris FELD]

 Could you paste a run of this state in with the logging level at DEBUG?

I would break that up into multiple  state files having them include each other and setup require's.

[Jon Langemak]

Boris - When you say debug level do you mean running the salt-master and minion in debug mode?  Then executing the state?  Or were you looking for a different debug?

[Jon Langemak]

This is how I have it currently broken up...

#python-pip:

  pkg.installed

six:

  pip.installed:

    - reload_modules: True

    - upgrade: True

    - require:

      - pkg: python-pip

#docker-py:

  pip.installed:

    - reload_modules: True

    - require:

      - pkg: python-pip

#Install docker, enable it, and run it

docker:

  pkg:

    - installed

    - reload_modules: True

  service:

    - running

    - enable: true

Any suggestions you have would be appreciated.  Thanks!

[Boris FELD]

Yes please, it's only the minion side that will be interesting

[Jon Langemak]

Here it is - let me know what you think.  Thanks!

From what I can see on the log, docker-py install correctly and salt correctly tries to lazyload docker.pulled but fails to load it. Do you have multiple python version on your system, maybe the command used to install docker-py ("/usr/bin/pip2 install 'docker-py'") install it somewhere salt couldn't reach.

Thanks for looking at that.  Maybe Im missing something, but if its somewhere that salt cant reach how does reloading the salt client help?

Hi Jon

I am having the same problem as you now in 2017. Were you able to solve your problem?

Thanks,
